Abstract: ABSTRACT OF THE DISCLOSURE           A sliding weight scale includes a recirculating ball spindle mounted in a balance beam arranged to pivot about a swivel axis.  The spindle extends perpendicularly of the swivel axis of the beam.  A sliding weight is engaged via a nut with the spindle.  A gear wheel is fixed to the spindle and is driven by another gear wheel fixed on the base plate of the scale.  A hand wheel drives an intermediate gear assembly which, in turn, drives the gear wheels and the spindle.  The gear wheels driving the spindle are located in a vertical plane containing the swivel axis of the balance beam.  By the use of the recirculating ball spindle, the displacement forces acting on the sliding weight are kept small so that dimensional variations occurring in manufacturing and assembly have a negligible effect on the weighing accuracy of the scale.

Abstract: ABSTRACT OF THE DISCLOSURE         A 4800 bit-per-second full duplex modem is described which utilizes the full bandwidth of ordinarily available dial-up telephone circuits for transmission of data in both directions in different pass-band portions thereof.  The two pass-bands overlap in about the middle of the telephone band in order to fully utilize that bandwidth for high speed data transmission.  The overlap is less than that which will cause a greater error rate than desired from remote echos of transmitted data.  Local echos, which are much stronger, resulting from the overlap bandwidth portion are cancelled by an echo cancelling technique.  Local echo cancelling is accomplished at the baud rate, generated in each modem, for substraction from a received signal; a cancellation signal is generated from a time varying system that depends upon the modulating and demodulating carrier signals.

Abstract: CERAMIC FIBER FOAM AND METHOD FOR MAKING SAME            Abstract of the Disclosure Ceramic fiber is co-dispersed in a liquid medium together with a heat curable organic binder, and the mixture is beaten preferably with small amounts of a crystallizable salt and fillers.  Upon beating, the mixture is foamed, and the foam is then heated to cure the binder, evaporate the liquid, and stabilize the foam.  The foam may be used as is, but is preferably further heated to decompose most of the organic binder and to cause bonding between intersecting fibers by the salt, thereby resulting in a stable foam that has excellent high temperature properties.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for recovering zinc from zinc con-taining sulphidic material which also contains iron to gether with lead and/or silver includes leaching the material under oxidizing conditions at a temperature in the range of from about 130 to about 170°C in aqueous sulphuric acid solution with a stoichiometric excess of sulphuric acid relative to the zinc content of the material of from about 40 to about 100% to produce an undissolved residue containing a major proportion of lead and/or silver and a leach solution containing a major proportion of the zinc and iron.  The residue is separated from the leach solution and treated to recover lead and/or silver values.  The leach solution is treated to recover zinc by feeding the solution to another process in which zinc-containing material is treated to recover zinc and which includes an iron-precipitation step.  The other process includes roasting zinc and iron containing sulphidic material to produce a zinc oxide and zinc ferrite con-taining material, which is then leached in a weak aqueous sulphuric acid solution to dissolve zinc oxide and pro-duce a leach solution containing dissolved zinc and a zinc ferrite containing residue.  The residue is separated from the leach solution.  Zinc is recovered from the leach solution, and the zinc ferrite containing residue is leached in a strong aqueous sulphuric acid solution to dissolve zinc ferrite and produce a leach solution con-taining dissolved zinc and iron and a residue, with the strong aqueous sulphuric acid solution comprising at least a portion of the leach solution containing a major pro-portion of zinc and iron.  The leach solution containing dissolved zinc and iron is separated from the residue. Ferric iron in the leach solution is reduced to ferrous iron, and the ferrous iron is neutralized and hydrolyzed under oxidizing conditions to precipitate at iron com-pound, and the iron compound is separated from the remaining solution.

Abstract: Lock Picking Tool Abstract A picking tool adapted to open a cylinder lock of the axial pin tumbler type having its tumblers arranged in a coplanar configuration, includes a planar torquing core insertable into the lock keyway in a longitudinal direction, a plurality of longitudinal guideway channels formed on opposing faces of the core, and respective tumbler probes longitudinally reciprocable in the channels. A holder, which acts as a handle for manipulating the picking tool, also serves as a housing surrounding the core and the probes.  The holder is formed with a pair of radial openings in opposite sides thereof which receive respective brake segments for exerting a frictional drag on the probes.  An adjustable hoop clamp surrounds the brake segments for manually adjusting the frictional drag, so that the proper tumbler displacement action can be achieved.  Setscrews are threaded into the body of the holder for clamping the probes in their final tumbler-displacing positions.  At the rear of the holder, the tail ends of the probes fan out circularly so that they can be more easily manipulated individually.  The probes have indicia from which the lock code can be read out after the probes reach their final positions.

A counter is provided having a number of counts equal to the number of flash-eclipse pairs required.   A timing pulse generator is selectively controlled to produce timing pulses during each count that are temporally spaced in accordance with the flash-eclipse time durations during each count.   Certain ones of the timing pulses serve to clock the counter.   Lamp control pulses are generated during each count  for  energizing  the  lamp  for  the preselected time duration.   A sync pulse is generated at the beginning of every flash and a second pulse during the first flash in a sequence.  These pulses are externally available and are communicated to other flasher units for synchronization.  The unit will also synchronize to incoming sync pulses.  A photocell circuit inhibits flashing during daylight periods.

Abstract: ABSTRACT OF DISCLOSURE         A multiple thermocouple system for rapidly monitoring wall temperatures of a metal vessel and identifying those thermocouples having voltages and temperature readings above a predetermined level.  In the system, a number of first metal insulated conductor wires are metal bonded to the metal vessel to provide hot first junctions, and a second conductor utilizes the vessel metal wall as a portion of the conductor together with an additional metal insulated conductor wire connected to the metal wall.  The conductors of each thermocouple pair are connected to the terminals of a rapid switching device and sub-sequently connected by the switching device to a voltage measur-ing means, which can be a digital readout type millivoltmeter.      If desired, the voltage output of each thermocouple pair can be compared by a computer with the voltage output from a conven-tional dual conductor reference thermocouple attached to the vessel wall to determine temperature deviations.  Also, the voltage readout for those thermocouples showing temperature deviations exceeding a predetermined amount can be conveniently displayed on a cathode ray tube screen.
